AEROPLANE. I

Application filed November 3, 1925. Seria1 No. 66,456.

. The object of my invention is to simplify, cheapen and render more safe and eiiective both the construction and operation of aeroplanes generally, a distinctive feature being the dispensing with the use of propeller I blades and the hydro-carbon motors by which they are driven, thereby "eliminating noise and danger'of fire and explosion,--

the invention consisting substantially in the substitution of vibratory. wings in lieu of the usual screw blade propeller, and of electro-magnetic drive means 1n lieu of gas motor, all as hereinafter fully set forth and described and claimed specifically, an inci dental advantage attained being the electrical control of all operations of the mecha 'ni'sm involved.

- tical form and construct1on of plane or operative parts shown by way of exempli-fication, since changes may be made in minor details, and equivalent mechanical expedi ents resorted to with like results, and without departing from'the spirit and intent of my invention in this respect.

With this understanding Fig. 1, represents a side elevation of my improved aeroplane;

The forward part of thebodv A, oi the aeroplane is provided with the usual fixed top and side planes P, P, on the rear edges of each of which are articularly mounted series of vibratory propulsive wings 2.0, made up of like units, one of which is shown in detail in Figs. 3 and 4, eachconsisting of a wing blade w, attached to one end of an elastic resilient plate w, the other end of said elastic resilient plate 10, being rigidly secured to the rear edge of one of the body planes P, and the wing blade 11), being tapered gradually in thickness to the rear end thereof.

Near its forward extremity each wingblade 20, formed. with an armature a, and on either side thereof are positioned electro-i'nagncts m", m, .the cores of which face the armature a, and alternately attract it as the clectro-magnets m, are energized sueces-" sively. The shifting of the electric current from one magnet to the other is effected automaticallyby 1 means of a contact piece *1/1 on the elastic resilient wing supporting plate w, which engages alternately with the contact points m, m, connected each with the coil of one of the electro-magnets m, the coils ofthe latter being in turn connected indirectly with a storage battery' S, shown. symbolically in Fig. 3, of the drawings, which figure also illustrates the co-relation of the electric circuit control means C, shown upon a larger scale and in detail in Figs. 9 to 13 inclusive, of the drawings.

The tail propulsive wing blades are mounted, actuated, and controlled in substantially the same way as the pane propulsive wings, except that they are pivotally supported, as at y, Fig. 6, on brackets secured to the magnets m, m. 4

D is the rudder actuated by well known means connected therewith through the tube ail, positioned centrally on the rear framed,

the aeroplane A.

The electric circuit control means C, consists essentially ofa rotor R, on the shaft '1',

sion of three such "difie rential time commutators, although I do not restrict myself in this/ respect, since any plural number there-.

of may be used, as may be found most expedient in attaining desired variations in speed of propulsive wing action.

In the arrangement illustrated in Figs. 9 to 12, inclusive, the commutator K, is provided with twelve peripheral contacts Z2;

the commutatorli with eight peripheral 1'0 contacts 70 and the-commutator K with four peripheral contacts 76 'The rotor shaft 1', is hollow, and thecommutators K, K K are channeled radially to accommodate the conductive wires which connect each contact platellc, 72 70 with an "axial wire a, (see Fig. 11) which extends through the-shaft r, to the left haudbean ing E, and to accommodateconductiveflires to an axial wire 6, "(see Fig. 12) which extends through the shaft 7*, to the right hand bearing E. p 3

Hence, as the rotor- R, turns its shaft 7*,

alternately connected contact plates on each commutator-K, K K will be brought successively into engagement with the brushes i3, 13, B which arewire connected Wltll" the switchboard B, the key lever b, of which'is electrically connected with one side of the storage battery plant S, while the bearings E, E,- are in electrical connection with the other-side of said storage ba'ttery plant S. As a consequence of this arrangement the electric currents transmitted to the opposed electro-magnets m, m, included in the system of wiring will be energized alternately, thereby causing them to alternately attract the armatures a, and thus vibrate.

the propulsive wings 'w,w.

The bearings'E, E, are duplicates in so far as connection with the axial wires 6, e, are concerned, in thateach of said flXlal wires '6, e, terminates in a disc head e",

disc head 0, rotates with the rotor shaft 7',

whereas the elastic resilient contact an, is,

relatively, stationary,maintaining electrical contact with said disc head 0", without interfering with the rotation thereof.

It is thus obvious that by means of the key lever b, on the switch board B, the speed of vibration of the propulsive Wings w, may he varied within certain prescribed limits and in accordance with requirements. What I claim as my invention and desire to secure by Letters Patent, is

In combination with an aeroplane of the character designated, a plurality of vibratory propulsive wings mounted on the planes thereof and a plurality of propulsive wings mounted on the rear portion, thereof, electromagnetic: means for actuating said wings, and means forvarying the speed of operation, concisting of a switch board, a rotor, and a plurality of commutators of different diameters interposed in the opera tive electric circuit, substantially in the manner and for the-purpose set forth. i ALBERT WVORMAN.
